FRUlT-EVAPORATOR.

SPECIFICATION forming part of Letters Patent No. 272,927, dated February 27, 1883.

Applicationfiled March 3,1882. Renewed December 11, 1882. (No model.)

To all whom it may concern Be it known that we, JOHN WILLIAMS and JAY S.WILLrAMs, citizens of the United States, residing at Kalamazoo, county of Kalamazoo, State of Michigan, have invented a new and useful Fruit-Evaporator, of which the follow ing is a specification.

Our invention relates to fruit-eraporators which are heated by steam.

It has for its object certain improvements in the construction and arrangement of parts, the same being set forth in the following detailed description. 1

In the accompanying drawings, forming a part of this specification, Figure 1 is a perspective view of our improved pipe steam-heater; Fig. 2, a cross-section on line 1 2 in Fig. 3; and

Fig. 3, a compartment to our evaporator inclosing the heater in Fig. 1, showing its relation to the fruit-racks. I

B is a horizontal steam-supply pipe, shown broken at each end, the design being that it may be extended in either direction, in order that other heaters may be connected with it when forming a large evaporator containing many compartments, such as A, Fig. 3. This supply-pipe may be connected with any boiler or steam-supply desired. B is a similar horizontal pipe parallel with pipe B, and serves as an exhaust or waste pipe for carrying away the steam from the several heaters afterserving its intended purpose. With these pipes B B are deta'chably coupled the four standards a a, formed of detachable parts of pipe, and provided with a plug, a a, in the top, showing that they may be continued by adding other joints, according to the size of the compartment A. With these standards a a. are detachably coupled U-shaped heaters, consisting of sides 0 c and end 6. These ends are disconnected from standard-pipes a a, and a1- ternate in reverse order of location throughout the device. Standards a. a are also provided with stop-cocks o e, near the lower end, where said pipes join the horizontal pipes, for the-purposeof governing the supply of steam or heat for each device, and to shut the steam entirely oft from the heaters of any compartments not desired to be used.

We form the evaporator with one or more compartments, side by side, above or in front or rear, as desired, the construction of a single compartment being shown at A. The front inclosure is provided with the usual doors,F F,

for taking out and putting in fruit-racks, and

with doors E and w, for supplying the device in the space otherwise occupied by said pipes,

and obviating a necessity of slotting the cleats t t to fit around them.

In Fig. 3 fruit racks or screens M are shown located on cleats t it, two between the heaterpipes c c, and alternating with them. These racks are disconnected from the heaters and from each other. The bottoms of the racks are made of wire screeningor slats in the usual man ner. By the nseof pipe-heaters in this apparatus,theairenteringattheaperturebelow doorE in Fig. 3 passes directly up through the screens and pipes, where it is heated, and evaporates the moisture from the fruit. This is deemed a great improvement over alternating steam pans or chambers heretofore in use, which retard the air and heat the fruit unduly. The advantage of this arrangement of heater-pipes in contrast with a connected circuit or coil is that a given degree of heat may be more quickly distributed and accurately sustained in all parts of a given compartment.

What we claim is.

1. In a fruit-evaporator, a heating device consisting of the standard-pipes and the U- shaped heaters, provided with means for transmitting steam to and from said device, all substantially as set forth.

2. In a fruit-evaporator, the combination, with a steam heating device having the standard-pipes, of an inclosed compartment, the ends thereof being provided with vertical openings to receive said pipes, substantially as described and shown.
